Vampire Bullet from comics

This is a replica of Vampire Bullet appeared in issue #57 of the Italian comic Nathan Never (publisher Bonelli).
I used 1x607D bearing under the head to simulate the head rotation and some glue for the flaps in the body and in the head.
i printed all parts at 1.05 scale so the bearing fit better.
If needed i put some tape around bearing to fit perfect in the head.
(i could modify the cad project but i preferred to work in the end)
I attached the page of comic where you can see it.
